To all whom it may concern:

Be it known that I, ALEXANDER P. WHITE, a citizen of the United States, residing at Caldwell, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Fibrous Building Material, of which the following is a specification.

This invention relates to a novel and practical building material available chiefly for lathing, although it may be used for other purposes in building construction.

To this end, the invention has for its object to provide an improved building material and to cheapen the cost of buildingconstruction, and primarily involves a novel manner of combining a fibrous corrugated sheet with stifiening and reinforcing materials in the various ways shown in the accompanying drawings, in which Figure 1 is a perspective view of one form of building material embodying the present invention.

Fig. 2 isa cross sectional view of the form of construction illustrated in Fig. 1.

Fig. 3 is a view similar to Fig. 2 showing a modified form of construction.

Figs. 4 and 5, 6 and 7, 8 and 9, 10 and 11 are paired views respectively in plan and section of various modifications of the invention as to the arrangement of the metallic members and themethod of disposing the same for engagement by the plaster.

Figs. 12 and 13 are similar plan views of additional modifications of the material.

Fig. 14 is a view similar to Fig. 3 illustrating an embodiment of the invention wherein the corrugated sheet and the metal elements seated therein are inclosed between plain facing sheets which are imperforate throughout.

Like reference characters designate corresponding parts in the several figures of the drawings.

Referring to the conditions leading up to the present invention, it is well known that in the use of articles of this nature composed of metallic elements, as for example wire lath or expanded metal, there is an objection to the liability of the metallic parts to corrode or rust. And accordingly, it is the purpose of the present invention to provide a building material wherein the metal parts are completely covered, as well as to provide a novel construction of building material which when used as a lath requires much less plaster to form the wall thereof than is required by the usual woven wire and expanded metal" fabrics. In the use of allmetal fabrics, much plaster is wasted or lost by passing through the meshes of the fabric, and a heavier coat of plaster is necessary to make an even surface, and it is these objections particularly which are successfully met and overcome by a fibrous building material constructed in accordance with the present invention.

The improved building material claimed herein, primarily includes a sheet of fibrous corrugated body material A, such for instance as a sheet of corrugated paper, combined with a flat facing sheet B of paper or other fibrous material, as shown in all of the figures of the drawings. Through the valleys formed by the corrugations, there are '75 According to the embodiment of the in- 85 vention shown in Figs. 1 and 2 of the draw- I ings, the corrugated body sheet A is illusr trated as having the paper or equivalent facing sheet B glued or otherwise suitably fastened upon one side of the sheet, and by9 o reason of having a fastened union with the ridges of the corrugations becomes a permanent part of the body material and contributes to its stiffness and durability. Also, the facing sheet acts as a covering for the grooves of the corrugations at one side of the sheet, and thereby holds in place the metallic members or rods C which are placed in any desired number in the grooves according to the requirements of the wall or ceiling to be constructed.

In Fig. 3 of the drawings, there is shown the expedient of applying a facing sheet upon both sides of the corrugated sheet where it is desirable to obtain extra stifiness and strength for the building material or form. The additional facing sheet in this modification is designated'by the reference letter F, and in all other respects the construction and use of this form of the inven- 11o In this embodiment of the invention, the rod containing grooves covered by the facing sheet B permits the plaster or cementi-- bers or rods, so that the plaster applied to the surface of the supporting body will press through the openings and about the rods C in the manner indicated in Figs. 2 and 3 of the drawings. According to the form of the invention shown in Figs. 4 and 5 of the drawings, the metallic members are shown in crossing relation, and at their points of crossing exposed'to a considerable degree for direct engagement by the cementitious material. Referring to this form of the invention, it will be observed that the sameincludes in addition to the main corrugated sheet A, the facing sheets B and E respectively upon opposite sides thereon and supplemental metallic members or rods F which arearranged in crossing relation to the rods C and the grooves of the corrugated sheet, and are held directly on the ridges of the corrugations by the facing sheet B. In the plane of the point of crossing of the metallic members C and F, the facing sheet B is provided with key openings G of crossform, which provide an eflective means of insuring the positive and permanent interlocking engagement between the plaster and the metallic members of the structure.

Substantially the same combination of features is involved in the forms shown in Figs. 6 and 7 of the drawings with the single exception that the key openings G in this construction pierce both of the facing sheets, thus rendering the material reversible and providing for a more extensive area of keying the plaster about the metallic members at their points of crossing. The same general idea of the modification shown in Figs. 4 and 5'is preserved in the modification of Figs. 8 and 9, with the exception that in the latter form of construction, there may be employed comparatively stout metallic members or rods C, located in the grooves of the corrugated sheet and employed without supplemental crossing rods or wires. Also, in this form of construction shown in Figs. 8 and 9, portions of each metallic member or rod are exposed at intervals through key openings G formed in one of the facing sheets and dis posed longitudinally of the metallic member or rod.

In Figs. 10 and 11 of shown a form of construction which is the the drawings, is

same in all respects as that of Figs. 8 and -9, with the exception that the key openings G pierce both facing sheets and the inter vening corrugated sheet. u

Another method of exposing the metallic members or rods for direct engagement by the plaster is that shown in Fig. 12 wherein the main and supplemental metallic members C and F are employed, and each of which is exposed at intervals through key openings G and G respectively in one or both of the opposing sheets, and in Fig. 13 is shown a form of the invention which illustrates how the key openings G in one or both of the facing sheets may be of elliptical or other design to expose the members at their points of crossing to a comparatively large area of the plaster or cementitious material.

In all of the embodiments of the invention so far described, the metal, to some extent at least, is disposed for direct engagement by the cementitious material, but the principal objects of the invention may be attained by having imperforate facing sheets B which entirely cover and protect the metallic rods in the valleys of the corrugated body sheet as shown in Fig. 14 of the drawings. In this-form of the invention the plaster will be applied directly to either side of the material.

Furthermore, another feature of importance that may be embodied in the present invention is that of providing any desired number of corrugations of the body sheet with cementitious fillings 8 placed in the valleys or grooves, and which when hardened and set adds to the strength of the material. See Figs. 1, 2, 3 and 5.

Also, it may be found preferable in carrying out the invention to treat the body material with a compound for the purpose of imparting waterproofing and fire-resisting characteristics thereto, as for example a compound consisting of a mixture of silicate of soda and aspha-ltum or oxid of iron.

Various changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention, or without departing from the scope ofthe appended claims.

A building lath comprising a series of spaced apart metal stringers, a supporting body for the metal stringers conslsting of a sinuous fibrous sheet having a multiplicity of contiguous corrugations, in the valleys of at least some of which corrugations the metal stringers are longitudinally seated, and a facing sheet united with the corrugated sheet and having openings communicating with valleys of the corrugations.
